摘    要：贯通工程的质量直接影响矿山的安全生产,提高贯通测量精度是确保贯通工程质量的关键。详细介绍了黑龙江乌拉嘎金矿西露天采场70中段巷道硐口点到竖井70中段外延巷道600 m贯通测量方法,并对贯通测量进行了误差预计和精度分析;提出了贯通测量施测中应注意的问题,值得借鉴。

Abstract: The quality of breaking through influences the mining production safety directly.And the survey accuracy is the key point to ensure the breaking through quality.The paper introduces the survey method of 600 m-long breaking through between tunnel of 70 m midsection in the west openpit and the extension tunnel of 70 m midsection in the shaft.The survey error estimate and accuracy analysis in Wulaga gold mine is carried out as well.Some attentions in breaking through survey are proposed for references in future.
